Draft: AMD package descriptions for ROCm
Co-authored by: @x-KHauge
This MR adds package descriptions for the complete ROCm toolchain (all relevant llvm components) and HIP. Select libraries needed for running synthetic benchmarks are provided (only HPCG and BabelStream for now). This includes descriptions for GPU-aware MPI enabled for AMD GPUs.
The main focus here is on the core toolchains (interface between LLVM and ROCm) and to provide a solid foundation to build off of. We would really appreciate any input and suggestions for how we can improve on this.
